Digital Marketing Contract Spain (Contrato de Marketing Digital)

A Digital Marketing Contract Spain (Contrato de Marketing Digital) is a formal written agreement between a client business (cliente or empresa contratante) and a digital marketing agency (agencia de marketing digital) or freelance digital marketing professional (profesional autónomo) under which the agency undertakes to plan, execute, and optimise digital marketing activities — including search engine optimisation (SEO), search engine marketing (SEM — Google Ads, Bing Ads), social media management (gestión de redes sociales), content marketing (marketing de contenidos), email marketing, and programmatic advertising — on behalf of the client, in exchange for a monthly retainer or project-based fee, governed principally by Article 1544 of the Código Civil (CC) on the arrendamiento de servicios, and subject to the extensive digital regulatory framework applicable in Spain.

The Ley 34/2002, de 11 de julio, de Servicios de la Sociedad de la Información y de Comercio Electrónico (LSSI-CE) is the foundational law governing electronic commercial communications and digital marketing in Spain, implementing EU Directive 2000/31/CE on electronic commerce. Article 19 LSSI-CE regulates commercial communications (comunicaciones comerciales) by electronic means — email, SMS, social media direct messages — requiring that all commercial communications be clearly identified as advertising, identify the sender on whose behalf they are sent, and comply with the recipient's opt-out rights. Article 21 LSSI-CE prohibits unsolicited commercial electronic communications (spam) without the prior explicit consent of the recipient.

Data protection obligations are central to digital marketing activities in Spain, governed by Reglamento (UE) 2016/679 (RGPD — Reglamento General de Protección de Datos) and Ley Orgánica 3/2018 (LOPDGDD — Ley Orgánica de Protección de Datos Personales y garantía de los derechos digitales). Digital marketing activities inherently involve personal data processing — email lists, web analytics tracking (cookies), targeted advertising based on user behaviour, CRM data management, and retargeting campaigns. The digital marketing agency, when processing personal data on behalf of the client, typically acts as encargado del tratamiento (data processor) under RGPD Article 28, and must sign a data processing agreement (acuerdo de encargo de tratamiento) with the client specifying the categories of data processed, the processing purposes, the technical and organisational security measures implemented, and sub-processor chains (Google Ads, Meta Ads, email platforms).

The Ley Orgánica 3/2018 (LOPDGDD) Article 22 specifically regulates cookie-based tracking and analytics, requiring that websites display a cookie consent banner (aviso de cookies or cookie banner) providing granular consent for different cookie categories — necessary cookies (functional), analytical cookies, and advertising/marketing cookies — in compliance with both LOPDGDD and the RGPD requirements interpreted by the Agencia Española de Protección de Datos (AEPD) through its guidance on the use of cookies (Guía sobre el uso de las cookies, updated 2023).

For campaigns involving influencer marketing (marketing de influencers), the Ley 34/1988 General de Publicidad and LSSI-CE Article 20 require that sponsored content — publicaciones patrocinadas — be clearly identified as advertising through disclosures such as #publicidad or #ad visible to the audience, and the Comisión Nacional de los Mercados y la Competencia (CNMC) has issued guidance on this requirement. The Código de Conducta sobre el Uso de Influencers de la Publicidad Digital, promoted by Autocontrol (Asociación para la Autorregulación de la Comunicación Comercial) and IAB Spain, provides voluntary industry standards that professional agencies typically adopt.

A Digital Marketing Contract Spain is required whenever a business retains a digital marketing agency or freelance specialist to manage its online marketing activities on an ongoing or project basis, formalising the agency's authority, obligations, and access rights to the client's digital platforms and advertising accounts.

A Contrato de Marketing Digital is needed when a retail or e-commerce business (tienda online) appoints an agency to manage its Google Ads and Meta Ads campaigns — the contract establishes the agency's authority to access and operate the client's advertising accounts, defines the monthly budget allocation, sets performance targets (ROAS — Return on Ad Spend, CPA — Cost per Acquisition), and governs the ownership of campaign data and creative assets.

The contract is required when a company engages an SEO specialist (especialista en posicionamiento web) to improve its search engine rankings (posicionamiento en buscadores) — defining the scope of technical SEO audits, on-page optimisation, content creation, link building strategy, and the key performance indicators (KPIs) used to measure SEO progress over a rolling monthly retainer.

A Contrato de Marketing Digital is needed when a business outsources its social media presence — Facebook, Instagram, LinkedIn, TikTok, Twitter/X — to a social media manager (community manager or social media manager), formalising content planning, publication calendars, community moderation, influencer collaboration management, and the brand's voice and content approval process.

The contract is required when an agency manages email marketing campaigns using platforms such as Mailchimp, HubSpot, Salesforce Marketing Cloud, or equivalent — the contract must address the RGPD and LSSI-CE obligations for commercial email communications, the handling of opt-out requests (bajas) within 10 days as required by LSSI-CE Article 22, and the ownership and security of the client's subscriber database.

A Contrato de Marketing Digital is needed when a company retains a content marketing agency to create blog articles, video content, infographics, white papers, or case studies for SEO and brand awareness purposes — defining content topics, editorial calendar, SEO keyword targets, quality standards, intellectual property ownership (who owns the produced content — typically transferred to the client upon full payment), and the exclusivity period before content can be reused.

The contract is also required when a business participates in influencer marketing campaigns through a marketing agency acting as intermediary between the brand and the content creators — the digital marketing contract governs the agency's obligations to select appropriate influencers, negotiate collaboration agreements on the client's behalf, confirm LSSI-CE publicidad disclosure compliance, and measure campaign results against agreed metrics.

Under the Ley de Sociedades de Capital (LSC) RDL 1/2010, the Registro Mercantil maintains the register of Spanish companies. The Código de Comercio 1885 governs commercial obligations. The Agencia Estatal de Administración Tributaria (AEAT) administers Impuesto sobre Sociedades (IS) under Ley 27/2014. The Comisión Nacional de los Mercados y la Competencia (CNMC) enforces competition law. The Código Civil governs general contractual obligations under Article 1255.

A valid Digital Marketing Contract Spain under the Código Civil Article 1544, LSSI-CE, and RGPD must contain the following essential elements to be enforceable and to comply with Spain's digital regulatory framework.

Identification of Parties: Full legal name, NIF/CIF, and registered address of the client (cliente) and the digital marketing agency or freelancer (agencia or profesional autónomo). The agency's relevant credentials — IAB Spain membership, Google Partner or Meta Business Partner certification, ISO 27001 certification for data security — should be referenced. For freelance professionals, their RETA (Régimen Especial de Trabajadores Autónomos) registration and epígrafe de actividad económica (IAE classification) must be confirmed.

Scope of Services: A precise description of the digital marketing services to be provided — specifying each service channel (SEO, Google Ads, Meta Ads, LinkedIn Ads, email marketing, social media management, content marketing), the specific activities included within each channel, and any activities expressly excluded. The scope must clearly state which digital platforms and advertising accounts are covered and the level of the agency's management authority (strategic, executive, or advisory).

KPIs and Performance Metrics: Quantified performance targets aligned to the client's business objectives — website organic traffic growth (%), Google Ads click-through rate (CTR) and conversion rate, social media follower growth and engagement rate, email open rate and click-through rate, lead generation volume (CPL — Cost per Lead), e-commerce ROAS, and monthly reporting obligations. The methodology for measuring and attributing performance (Google Analytics 4, Meta Business Suite, search console data) must be agreed to avoid disputes.

Access Rights and Platform Management: The scope of the agency's access to the client's Google Ads account, Meta Business Manager, Google Analytics 4, website CMS, and email platform — whether as administrator, editor, or analyst — and the security protocols for credential management (MFA — multi-factor authentication, access log maintenance). Termination of access immediately upon contract expiry or termination must be addressed.

Intellectual Property: Ownership of all creative materials produced — advertising copy, images, videos, landing pages, blog content, social media graphics — including whether the client receives full assignment (cesión) of intellectual property rights under Ley 23/2006 (Ley de Propiedad Intelectual — LPI) upon payment, or whether the agency retains copyright and grants only a licence. The agency should retain the right to include client work in its portfolio (with confidential data removed) unless the client expressly prohibits this.

Data Protection and LSSI-CE Compliance: A RGPD-compliant data processing agreement (acuerdo de encargo de tratamiento) as an annex or within the contract body, specifying: categories of personal data processed (user behaviour data, email subscriber lists, advertising audience data), the processing purposes and legal basis, sub-processors used (Google LLC, Meta Ireland, email platforms), technical and organisational measures, and data retention. LSSI-CE Article 21 compliance obligations for email marketing — consent verification, unsubscribe management — and cookie policy compliance under LOPDGDD Article 22 and AEPD guidance must be addressed.

Budget Management: If the agency manages paid advertising budgets on the client's behalf — Google Ads, Meta Ads, LinkedIn Ads spend — the contract must specify: who holds the advertising account (client owns the account; agency is a user), the monthly media budget amount and approval process for budget changes, the agency's management fee structure (percentage of media spend or flat monthly fee), and the invoicing process for media costs (direct billing from platforms to client, or agency billing to client plus management fee).

Contract Price and Payment: The monthly retainer (honorarios mensuales) or project fee, inclusive and exclusive of IVA (21%), with a clear scope of what is included. Payment terms under Ley 3/2004 de lucha contra la morosidad — typically 30 days from invoice date. Late payment interest at the official ECB reference rate plus 8 percentage points per Ley 3/2004. Any success-based bonus (variable remuneración) tied to KPI achievement should be defined with objective measurement criteria.

Confidentiality: Mutual confidentiality obligations protecting the client's business strategies, customer data, and proprietary information, and the agency's proprietary methodologies, tools, and processes — governed by the applicable confidentiality agreement (acuerdo de confidencialidad under CC Article 1258 analogy and Ley 1/2019 de Secretos Empresariales).

Termination: The contract term (typically 6–12 months minimum for SEO contracts, given the long-term nature of organic search results), notice period for termination (minimum 30 days), and post-termination obligations — transitioning access, delivering final reports, transferring ownership of advertising accounts and campaign data to the client.
